Abstract
The present invention relates to a pneumatic tyre for vehicle. Previous pneumatic tyre is to increase bonding force between the rim and tyre bead, and forms concavo-convex bonding section in bottom of the tyre bead, which besides greatly improves air tightness of the contact surface between the the rim and tyre bead, bonding force of rim and tyre bead is not improved as desired. The invention forms a antiskid device between said rim (1) arranged on the vehicle and bead section (2) of the tyre arranged on said rim, and presses the bead section of the tyre to the rim on bottom of the bead core by arranging bead plunger ring, such that skid condition between the tyre of the rim and the bead section is restrained, and the stability and comfort are improved, meantime, accident caused by emergency brake when vehicle turns can be pre-guarded.
Description
Invention field
The present invention relates to Pneumatic vehicle tire, more particularly, relate to the skidding that takes place between the tyre bead of the wheel rim that can suppress to install tire and tire, improve the stability of handling and take precautions against Pneumatic vehicle tire in advance in action of vehicle sharply turning and the incident accident of anxious glancing impact.
Background technology
General, the tire that combines with wheel rim is because of combining securely with wheel rim and mutual slip can not taking place.
But, vehicle is in the way of travelling when sharply turning, brish acceleration or anxious the parking, if wheel rim and tire slide on contact surface mutually, tire dallies around wheel rim, the propulsive effort of vehicle or braking force can not pass to tire, thereby the possibility that the substantial risk situation takes place is arranged, meanwhile, the problem of the escape of air of inside tires filling can take place.
Therefore, the inventor provides the bead part that can prevent tire that addresses the above problem and the wheel for vehicle (Korean utility model patent application 97-11243 number) of the slip between the wheel rim.
Making in first to file of the invention described above people forms concavo-convex joint portion in the contact surface of wheel rim and tire bead portion, in the bubble-tight while that wheel rim and tire contact surface are provided, its formation is not slided wheel rim and tire in a circumferential direction mutually, can improve turnability and deceleration and stopping performance.
But, find according to above-mentioned being installed in the process that test is travelled on the vehicle in manufacturing at the wheel of first to file and with it, though improved the air-tightness between wheel rim and the tire contact surface greatly, do not improved the binding force of wheel rim and tire bead as expected.
Summary of the invention
The present invention proposes in order to address the above problem, the objective of the invention is to, Pneumatic vehicle tire is provided, increase, prevent the generation of the skidding between the bead part of wheel rim and tire by the binding force that makes bead part and wheel rim portion, thereby improve ride comfort sense (preventing the abnormal vibrations of vehicle), have an accident in the time of can preventing the sharply turning action of vehicle and emergency braking simultaneously in advance.
To achieve the above object, the invention provides a kind of Pneumatic vehicle tire, the tyre bead trim ring that is provided with in the bottom of bead core, as skidproof device between the contact surface of the bead part that is installed in the tire of installing on wheel rim on the vehicle and the described wheel rim, described tyre bead trim ring comprises: installation portion, and it is equipped with the bottom of bead core; Pin is fixed described installation portion in the bottom of described installation portion, and the pressure force of trim ring is evenly disperseed.
Description of drawings
Fig. 1 is the section drawing at main position of the present invention;
Fig. 2 is the amplification sectional view of tyre bead trim ring of the present invention.
The explanation of preferred embodiment
Below, with reference to the accompanying drawings, to a preferred embodiment of the present invention will be described in detail.
Fig. 1 of accompanying drawing is the section drawing at main position of the present invention, and Fig. 2 is the amplification sectional view of tyre bead trim ring of the present invention.
As depicted in figs. 1 and 2, the present invention is provided with anti-skid device between wheel rim of installing on the vehicle 1 and bead part 2 contact surfaces that are installed in the tire on the above-mentioned wheel rim, it is configured to: tyre bead trim ring 3 is set, in the bottom of bead core 20, the bead part 2 of tire is pressed together on the wheel rim 1.
Described tyre bead trim ring 3 comprises: installation portion of installing in the bottom of bead core 20 31 and the homodisperse pin 32 of the pressure force that makes trim ring 3 that forms when installation portion is fixed in the bottom of described installation portion 31.
At least constitute more than one described pin 32, the vertical formation in ground that meets at right angles of the central member 321 that the bottom center of installation portion 31 forms and installation portion 31, the side pin 322 of the two bottom sides formation of installation portion 31 is formed slopely laterally.
The tilt angle theta of above-mentioned side pin 322 is preferably formed in about 30-40 ° the scope.
And, make the width W of above-mentioned installation portion 31 identical with the width of bead core 20, each pin 321 and 322 thickness T 1 minimum form more than 1 millimeter, and each foot length L is minimum to be formed more than 2 millimeters, and the thickness T minimum of installation portion 31 forms more than 1 millimeter.
The present invention of Gou Chenging is in the vehicle ' way like this, vehicle sharply turning, brish acceleration or anxious stopping, under the situation of take place sliding between wheel rim 1 and the tire, the bead part 2 of tire is squeezed to the surface of wheel rim 1 tightly, makes between tire and the wheel rim 1 skidding does not take place by trim ring 3.
In other words, friction force is to obtain by the power that acts on friction coefficient between the contacted two sides and the vertical direction, trim ring 3 plays a part the power of (when emergency braking, brish acceleration, sharply turning) raising vertical direction when squeegee action, thereby friction force is increased, suppress the skidding that takes place between wheel rim and the bead part.
The present invention is not confined to described embodiment, and technological thought of the present invention can adopt the mode of various deformation to implement in the scope of allowing.
As mentioned above, according to the present invention, not only improved its gas of contact-making surface part of wheel rim and tire Close property has also improved its associativity, has the turn performance of raising vehicle and the effect of braking ability Really.
